Patent CA-2162554-C (CA)
Title: High performance spiral-wound catheter
Inventor: SAMSON GENE
IPC: F16L11/12
Filed: 1995-11-09
Granted: 2000-07-18
Abstract: This invention is a surgical device.  In particular, it is a catheter suitable for accessing a tissue target within the body, typically a target which is accessible through the vascular system.  Central to the invention is the use of a stiffener ribbon, typically metallic, wound within the catheter body in such a way as to create a catheter having controllable stiffness.  The stiffener ribbon is adhesively bonded to a flexible outer tubing member so to produce a thin wall catheter section which is exceptionally flexible but highly kink resistant.          The catheter sections made according to this invention may be used in conjunction with other catheter sections either using the concepts shown herein or made in other ways.  Because of the effective strength and ability to retain a generally kink-free form, these catheters may be effectively used in sizes which are quite fine, e.g., 0.015" to 0.020" in diameter, and usable within typical vascular catheters.

Abstract: A portable radio telephone (5) communicates with base stations (1, 2) in a digital radio telephone system, such as DECT, employing TDMA transmission. The portable radio telephone is programmed with an algorithm which is operative to select a communication channel by storing a blind slot mask (7) representative of the time slots in each frame which are excluded, either by virtue of being occupied by the base station or by the portable radio telephone itself. Hence, any channel attempted and failed in an occupied time slot is excluded and marked blind in the blind slot mask. Further, the algorithm is operative to check the time slots for availability in a predetermined sequence which corresponds to the temporal sequence of the slots (or the reverse thereof) to promote orderly filling of the time slots at the base stations.

Abstract: A system wherein audio samples are added to a video signal, but within the time-frame allocated to video information, thereby displacing video data. Two audio samples are preferably placed in each video line: at the beginning, and at the end. When the video lines are "stacked" to form a video image, the audio forms noisy vertical stripes at the sides of the image, each of which is about 6 percent of the width of the image. The invention stretches the video image, to cover the stripes.

Filed: 1995-06-22
Granted: 2002-06-18
Abstract: A slag control shape (32) is releasably mounted on a cover for a molten metal vessel (10). An actuator (164) is connected to a slag control shape release member (100) to move the release member (100) from a first position engaged with the slag control shape (32) to a second position disengaged from the slag control shape (32) to allow the slag control shape (32) to descend into the molten metal vessel (10). Upon the occurrence of a predetermined condition, such as a predetermined weight of molten metal in the vessel (10) or a predetermined total time of molten metal discharge from the vessel (10), a controller (152) generates a signal to the actuator (164) to automatically release the slag control shape (32) into the vessel (10). The controller (152) is located remote from the actuator (164) and transmits the activation signal (164) to the actuator by radio frequency signals, directly through an electrical conductor, or to a light emitter which transmits a light beam to a photodetector mounted on the cover (28).

Abstract: An antenna for use at UHF and upwards has a cylindrical ceramic core (12) with a relative dielectric constant of at least 5. A three- dimensienal radiating element structure, consisting of helical antenna elements (10A - 10D) on the cylindrical surface of the core (12) and connecting radial elements (10AR - 10AD) on a distal end face (12D) of the core, is formed by conductor tracks plated directly on the core surfaces. At the distal end face the elements are connected to an axially located feed structure in a plated axial passage (14) of the core (12). The antenna elements are connected together by a plated sleeve (20) covering a proximal part of the core (12) which, in conjunction with the feeder structure, forms an integral balun for matching to an unbalanced feeder. Since the ceramic core fills the major part of the interior volume defin ed by the radiating element structure, the antenna is very much smaller than an air-cored antenna. It is also mechanically robust and electrically stable .

Abstract: An appliance timer has features to facilitate automated assembly or manual assembly. A timer housing base accepts timer components from two directions, and installation of components in either direction is along a straight axis. A motor in the timer engages a gear train which means a drive cam. The drive cam imparts motion to a camstack which then engages timer blade switches, and the blade switches operate the appliance. A subinterval is also supplied on the timer to allow periodic operation of a switch without the use of the camstack. The timer also features a quiet manual advance which removes the blade switches from communication with the camstack to allow an operator to select various timer programs without any of the clicking noises that are usually associated with timer program selection. Furthermore, a detent slider is positioned in communication with the camstack to provide a tactile feel for the operator of the timer when selecting between various timer programs.
